Arthur Alik-Lagrange and Martin Ravallion, "Estimating Within-Cluster Spillover Effects Using a Cluster Randomization with Application to Knowledge Diffusion in Rural India," Journal of Applied Econometrics, Vol. 34, No. 1, 2019, pp. 110-128. Two data sets and a Stata do file are zipped in the file alr-files.zip. These are ASCII file in DOS format. Unix/Linux users should use "unzip -a". - DATAlong.csv is the data in long format: one row is one individual, and variables measured in both rounds are reported twice ("xxxR1" for round one and "xxxR2" for round two) - DATAwide.csv is the data in wide format: one row is one individual in a given round of data - The Stata do file "alr-run.do" can be run using these data. Running this file in Stata (version 14) produces all tables and figures of the paper.
